High-pressure water, in combination with special chemicals, aids in the removal of graffiti, especially when the water is hot, as a quick rinser of the softened graffiti. Sometimes a pressurized mixture of air and sand, or water and sand, is used to blast off the surface of the vandalized area, etching the surface and making it extremely difficult to use high-pressure cleaning as a follow-up process. Sandblasting as graffiti removal often over cleans a surface and is capable of leaving a permanent scar on the surface.
Low-pressure washing is a common technique used in today's residential house washing market.Professional pressure washing contractors have used high pressure equipment in the past to clean residential homes, however, low-pressure, high volume pressure washing equipment has been introduced as an alternative along with the use of specific cleaning solutions to achieve effective cleaning with a very low possibility of damaging the property.
